Shower temperature changes

[Azalian]

If you use a flexible hose type shower head and move it from its socket on the wall, then hold the shower flow further down, say, on your thighs or knees, do you find that the water temp rises, (or seems to)?

On am I just imagining it?

I realise that letting the water fall down to the same point on the skin from higher up might cool the flow a little but I can't think that it would make that much difference.

My shower does the same, I think its because the water is hotter in some part of the pipe nearer where its heated and it moderates to normal temperature with the flow, I notice it goes cold for a few moments before it settles down to about 35degrees.

[rojash]

Mine does the same. I suspect it's because the hot water is gravity-fed from the tank above you, while the cold is under mains pressure.

[Teddio]

If the rate of water flow increases then the temperature of the water will fall. (and vice-versa)

[buildersmate]

Only if the device heating the water is an instant variety and is working at a constant rate of Watts. Otherwise, nonsense.

[wildwood]

rojash and Teddio have the right answer.

The instant heaters list their advantages as holding a constant temperature which I can personally attest to.

what, in writing?

[legend758duo]

its a trick of the light

[Azalian]

Thanks, legend, finally a sensible answer, I suspected light would be behind this problem somewhere.
lol

Teddio, if you lower the shower head surely that increases the head pressure so how would that raise the water temp?

[rojash]

If you lower the shower head it will increase the pressure of hot water from the tank, but will not affect the pressure of the cold water which is from the main. In other words, lowering the show head is the same as rotating the mixer towards the hot setting

[buildersmate]

Teddio is (presumably) referring to the lowering of the exit water temperature on an electric shower when the rate of water flow goes up. It's irrelevant in the case of this question, which is why I commented the answer was nonsense.

Don't be such a smartarse Meredith101, or I'll come over and put you on the naughty mat for 80 minutes.
